Assuming they settle for less than they could otherwise make. If Marner makes almost 11M on a 6 year deal EP would be well within his rights to ask for more on a deal that buys out more UFA years. He would be more comparable to Matthews. who only bought out 1 UFA year and still made over 11M.
EP isn't comparable to Matthews at all. Here are some of the top young C's in the league and their ELC production.
D+ 1
McDavid - 48 points in 45 games,
1.07 ppg
Matthews - 69 points in 82 games,
0.84 ppg
Mackinnon - 63 points in 82 games, 0.77 ppg
LD - 9 points in 37 games, 0.24 ppg
Eichel - 56 points in 81 games, 0.69 ppg
EP - Not in NHL
D+ 2
McDavid - 100 points in 82 games,
1.22 ppg
Matthews - 63 points in 62 games,
1.02 ppg
Mackinnon - 38 points in 64 games, 0.59 ppg
LD - 51 points in 72 games, 0.71 ppg
Eichel - 57 points in 61 games, 0.93 ppg
EP - 66 points in 71 games, 0.93 ppg
D+3
McDavid - 108 points in 82 games,
1.32 ppg
Matthews - 73 points in 68 games,
1.07 ppg
Mackinnon - 52 points in 72 games, 0.72 ppg
LD - 77 points in 82 games, 0.94 ppg (first season playing mainly with McDavid)
Eichel - 64 points in 67 games, 0.96 ppg
EP - 66 points in 68 games, 0.97 ppg
I'd say EP is on a similar level to Eichel through their ELC production. Both would be by far the most talented forwards on their team as well. I'd say EP is due for at least $10 million per year.
